NASA'S RUBBER RULER
Is there an official long-term temperature dataset that has not been updated/homogenized?
Is it statistically plausible that every 'updated' dataset would lead to an increased warming trend?
Randall Hoven writes at The American Thinker website:
"A funny thing happened on the way to determining how hot 2012 has been on a global basis: temperatures changed in 1880.
We've been hearing that 2012 has been the "hottest on record." I had written earlier that those claims were based on the contiguous United States only, or 1.5% of the earth's surface. The "global temperature" in 2012 through June was only the 10th hottest on record. In fact, every single month of 1998 was warmer than the corresponding month of 2012".
